Hey, thank you for fast response! That's exactly what I should do, but for some reason there was so much variables that I didn't realize the obvious course of action. To my surprise, the correct answer happened to be at the limits of t=0 and t=10 for both, so the resoults from the...

Homework Statement Temperature varies by function T(x,y,z)=3x + 4y + 2z Path is given by r(t)={ x(t)=\frac{t^3}{30}+\frac{16t}{9}+7 y(t)=-\frac{t^3}{120}-\frac{13t^2}{30}+28 z(t)=\frac{13t^2}{60}+\frac{4t}{3}-14 t\in \left[0,10\right] Question: What is the maximum and minumun temperatures of...

Yes, exactly thank you! I was using current source instead, so I had the resistors in parallel in equivalent circuit. I'd think that there's a solution in that configuration too, but this is fine for me.

Thanks for quick answers! I've tried the problem using the basic formulas of P = I^2 * R and P = V^2*R, but I only end up with a mess. I cannot see where the maximum power comes in. I'd think that you need to derivate the solution to get the maximum. I will end up with: Rx=(-PRy/(P-RyI^2))...

Hello, I want to ask the explanation for this basic problem. So I have 2 resistors in parallel(X and Y) and I want to maximize the power going through the resistor X, by choosing the resistance. This can be achieved only by choosing the same resistance for X, than Y has. Why is this so? I can...
